A CORPORATION OF ILLINOIS TAMPER-IPROOF SEAL FOR CONTAINERS Application filed October 6,1926. Serial No. 139,824. I

This invention relates to a novel construction of tamper proof seal for the nozzle or spout of a sheet metal container, the object being to provide a seal which must be removed before the contents can be poured out,

but which will not interfere with the application of the cap to the sealed nozzle or spout; and another object is to, provide a seal of this character which can be removed without injury to the nozzle'or spout, thus permitting the cap to be replaced .in case it is so desired, the seal being intended to show to the purchaser that the original contents of the package are intact at the time of-pur-, v

chase.

l The invention, therefore, consists in the details of construction hereinafter fully described and, set forth in the appendedclaim. Inthe drawings forming a part of this specification, Fig. 1 is a perspective view of a sheet metal container having its nozzle closed-by a cap; Fig. 2 is a top plan view of a nozzle with tamper proof seal therein and cap removed; and Fig. 3 is a sectional view of nozzle seal and cap.

;The cap and nozzle are now standard articles of manufacture and are both disclosed,

in my Patent No. 1,339,245.

Referringito the drawings, 10 indicates the cap'with fastening lever 13.

The upper edge of the nozzle or spout is 'rolled inwardly as shown at 14 and fitting into the mouth of the nozzle is a concavo-convex sheet metal'tamper proof seal 15 having an outwardly projecting flange 16, which is pressed firmly into wedging action with the inwardly rolled edge 14 of the nozzle or spout, the diameter of the seal itself bein such that it will just pass into the mouth 0 the nozzle and the outward curve of the seal make a tight fit upon the inwardly rolled edge of the nozzle.

nozzle mouth, the cap is fastened upon the end of the nozzle and effectively seals the same, and constitutes the main seal for the container.

The construction of the seal is such, and its position in the nozzle is such that it does not interfere with the application of the cap.

The sheet metal seal can have any legend or notice stamped thereon to indicate to the purchaser that the contents of the container have not been tampered with.

Having thus described my invention, what I claim is: a

The combination with a nozzle having an of a cup-like sheet metal seal adapted to fit into the mouth of said nozzle, the upper edge of said seal flaring outwardly and contacting with the inner convex edge of said inrolled portion, and a cap having a lining contacting with said inrolled edge portion of the nozzle and outwardly flaring edge of the seal.
